Bertia-related pyrenomycete?

HiI have here a pyreno with unitunicate asci that dissolve during maturity, the spores of which remind me of Bertia latispora. But the perithecia are smooth.
Descr.: 0.3-0.5 mm diam. Asci 6-8-spored, unitunicate, IKI-. Spores 23-35 x 8-11 µm, containing many minute LBs, 1-septate, very variable in shape.
Subaquatic on very rotten wood of Salix (or Populus), N-Germany (near Rehna, leg. T. Richter).

Re:Bertia-related pyrenomycete?
Most of the perithecia collapsing when dry, often laterally flattened, not from top as in Nitschkia.
any idea?

Sorry, I corrected in the previous message that the perithecia often collapse.

Dear Zotto,
Have you seen Munk pores? Your ascospores are slightly similar to those of Bertia pulneyensis.

Dear Maria
thanks, is it an Indian species? Where is it described? What do you mean with Munk pores?

Re:Bertia-related pyrenomycete?
Yes, it is an Indian species described by Subramanian & Sekar in Kavaka 18: 19-90 (1990). Munk pores are small perforations that appear in the ascomatal cells. they are typical (but not exclusive) of the Coronophorales. Here are 2 photos of them.

Re:Bertia-related pyrenomycete?
Dear Maria
so they are pores in the wall of the peridial cells? Are they in the lateral wall between the peridial cells? Present in every cell or only locally? I will try to locate this feature.

Re:Bertia-related pyrenomycete?
Dear Zotto, yes they are pores, not in every cell, randomly, 1 or2, sometimes more per cell, also in the lateral wall between cells. I´ve put a pdf of a paper in which you´d see more images.

Re:Bertia-related pyrenomycete?
Dear Virginia
I tried some photos but I could not verify Munk-pores. The problem is that oil drops can easily be taken for pores. Mounts are in KOH.
